Korloy is OK. But only OK not "Oh man do those things kick arse!"
A friend of mine has a Korloy "Ripper" mill for his 1992 Matsuura CNC machining center. The machine has a 6000 rpm spindle and no coolant-thru spindle. It does however, have TORQUE and he pushes tools hard. He complained to me one day that his Korloy cutter was noisy and the inserts (highly polished, uncoated) would start getting a "depth of cut notch" after 20 to 30 minutes of cut time.
I suggested he try a Walter F3040 cutter to see if it worked any better. The inserts for it (ZDGT150404R-K85 WXN15) are about 10% more and the cutter is at least 5x more money. After he started using it he texted me "the Walter cutter is about 30% less noisy, and I've made 300 gallons (1135 litres) of chips on a single edge." That's at least 30 HOURS of cut time. A week later I asked him how long the inserts lasted. He texted me back that he had made over 600 gallons of chips and finally indexed the inserts.
You won't see that kind of difference unless you were running the ODHT0504ZZN-G88 WXN15 inserts against the Korloy cutter.
